新兴的微技术领域为在真实的空间和时间以及单细胞分辨率下探索细胞趋化性开辟了新的可能性。趋化细胞感知化学梯度并响应化学梯度而移动,并在许多生理和病理过程中发挥重要作用,包括发育、免疫反应和肿瘤细胞入侵。由于微流控装置与细胞的尺寸接近,微流控趋化装置在两个主要方向上推进了传统的宏观尺度趋化性测定:一个是在细胞长度尺度上建立明确且稳定的化学梯度,另一个是使用先进的光学成像系统提供用于在细胞和分子水平上定量细胞反应的平台。在这里,我们提出了一个批判性的审查的设计原则,最近的发展,和潜在的能力的微流控趋化性测定解决问题,在生物医学工程领域的重要性。
The emerging field of micro-technology has opened up new possibilities for exploring cellular chemotaxis in real space and time, and at single cell resolution. Chemotactic cells sense and move in response to chemical gradients and play important roles in a number of physiological and pathological processes, including development, immune responses, and tumor cell invasions. Due to the size proximity of the microfluidic device to cells, microfluidic chemotaxis devices advance the traditional macro-scale chemotaxis assays in two major directions: one is to build well defined and stable chemical gradients at cellular length scales, and the other is to provide a platform for quantifying cellular responses at both cellular and molecular levels using advanced optical imaging systems. Here, we present a critical review on the designing principles, recent development, and potential capabilities of the microfluidic chemotaxis assay for solving problems that are of importance in the biomedical engineering field.
